Comment # 87 on bug 1177428 from Karl Mistelberger

Tested the following versions of kernel-firmware-amdgpu so far:

20200207-1.1
20200302-1.1
20200519-2.1
20200610-1.1
20200807-1.2
20200916-1.1
20201005-1.1
20201005-3.1
20201005-334.1
20201005-336.1
20201005-36.1
20201023-2.1

All of them fail on suspend to RAM/resume. The newest 20201023-2.1 adds some
additional trouble:
